With multiple deck heights and bore sizes up to 4.600, the Big M
Sportsman block gives you the versatility to build a wide variety
of engine combinations. A true priority main oiling system oils the
main bearings before the lifters for extra reliability.

Crankshaft tunnel has clearance for a 4.500 stroke crank with
steel rods without grinding.

True priority main oil system lubricates the main bearings
before the lifters. Our stepped main oil gallery (9/16 to 1/2 to
7/16) increases the flow of oil to the crank at high rpm, and our
front oil crossover eliminates internal oil leaks around the
distributor shaft.

Oil filter pad is drilled and tapped for an external oil
pump.

Available in traditional Gen IV style, or in Gen V
or Gen VI style with one piece rear seal.

Best prices I could find anywhere! Fast shipping. Will definitley buy from again.
